Abstract:

Two new records of Orchidaceae, Crepidium aphyllum (King & Pantl.) A. N. Rao and Thrixspermum pygmaeum (King & Pantl.) Holttum, are described based on fieldwork in southeastern Xizang (Tibet), China. Crepidium aphyllum is easy to distinguish from the heteromycotrophic species C. saprophytum by cylindrical pseudobulb, flat lip with rounded apex and erect dorsal sepal. Thrixspermum pymaeum (King & Pantl.) Holttum is similar to T. masciflorum A. S. Rao & J. Joseph, but differs from it by having inflorescence shorter than leaf, bracts spiralled, petals spathulate, lip concaved and 3-lobed, with a hairy callus connecting with column and emarginated middle lobe.
